Bridge Relief Joint Sealer Art. 588.03 CONSTRUCTION REQUIREMENTS
587.03 General. Before the sealer is applied, the concrete surface shall have
a minimum 48 hour drying period, and shall be cleaned with oil-free compressed air or wire brushes to remove all oil, grime, and loose particles. Surfaces that will not respond to cleaning by compressed air or wire brushes shall be cleaned by sandblasting. Care shall be taken to prevent the sealer from flowing over the edges and onto any concrete that is not to be sealed. The sealer shall be applied according to the manufacturer’s instructions, and information provided in the Department’s qualified product list.
587.04 Method of Measurement. This work will be measured for payment in
place and the area computed in square feet (square meters).
587.05 Basis of Payment. This work will be paid for at the contract unit price
per square foot (square meter) for CONCRETE SEALER. SECTION 588. BRIDGE RELIEF JOINT SEALER
588.01 Description. This work shall consist of sealing transverse relief joints
in the bridge decks.
588.02 Materials. Materials shall be according to the following.
Item Article/Section
a.Hot-Poured Joint Sealer ..................................................................... 1050.02 CONSTRUCTION REQUIREMENTS
588.03 General. The relief joint opening shall be formed to produce a
reservoir for the sealing material and shall be 1/4 in. (6 mm) wide by 3/4 in. (19 mm) deep. For concrete surfaces the relief joint shall be formed into the concrete. For HMA surfaces the relief joint shall be sawed into the surface. Immediately prior to pouring the sealer the joint opening shall be cleaned with compressed air so that it is free of all foreign and loose material and in a dry condition. The bridge deck relief joints to be sealed shall be free of cracked or spalled areas. Any cracked areas shall be chipped back to sound material before placing joint sealer. The hot-poured joint sealer shall be placed when the weather conditions are suitable, the air temperature in the shade is at least 40 °F (5 °C), and the forecast is for rising temperatures. Hot-poured joint sealer shall be stirred during heating to prevent localized overheating. The sealing material shall be applied to each joint opening according to the details shown on the plans or as directed by the Engineer, without spilling on the exposed deck surfaces. Art. 590.01 Epoxy Crack Injection All bridge relief joints shall be filled with sufficient sealer compound so that the top of the seal is flush with the top of the finished deck or wearing surface. Any sealing compound that is not bonded to the relief joint wall or face 24 hours after placing shall be removed and the joint shall be cleaned and resealed.
588.04 Basis of Payment. This work will not be paid for as a separate item,
but shall be considered as included in the unit price bid for the major item of construction involved. SECTION 589. RESERVED SECTION 590. EPOXY CRACK INJECTION
590.01 Description. This work shall consist of injecting cracks in structural
concrete with an epoxy bonding compound, or as designated in the contract.
590.02 Materials. Materials shall be according to the following.
Item Article/Section
a.Epoxy Bonding Compound ................................................................ 1025.01 CONSTRUCTION REQUIREMENTS
590.03 General. Only cracks or portions thereof that are 0.007 in. (0.2 mm) or
wider shall be injected. The areas for epoxy crack injection shall be prepared by removing all dust, debris, or disintegrated material from the crack by the use of oil-free compressed air and/or vacuuming. Any cracks holding oil or grease shall be chipped out to clean concrete. Horizontal and vertical cracks shall have suitable one-way injection ports installed every 6 to 18 in. (150 to 450 mm) or as required, depending on the width of crack, the horizontal or vertical location, and the dimensions of the member. The surface of cracks between the injection ports shall be sealed with a suitable sealing compound recommended by the supplier of the epoxy bonding compound. When the sealing compound is cured, mechanical pressure equipment shall be used to inject the epoxy bonding compound into the cracks. Injection shall begin at the bottom and progress upward when applicable. The injection pressure and epoxy bonding compound flow characteristic shall result in 90 percent penetration of the epoxy bonding compound. Injection shall continue until refusal, and without damage to the structural concrete. Pressure injection shall not exceed 500 psi (3450 kPa). When the epoxy bonding compound is cured, the injection ports and sealing compound shall be removed and the surface smoothed by stoning or grinding.
